Letters Patent No. 91,422, (lated June 15, 1869.

fI'MPRovED CURTAIN-FIXTURE.

The Schedule refened to in these Letters Patent. and making part of thesame.

To all whom it ,may concern:

Be it known that I, HENRY l. COOPER, of' the city, county, and State ofNew York, have invented a new and improved Gurtain-Fixture; and Ido-hereby deelare the following to be a full, clear, and exactdescription thereof, which will enable those skilled in the art to makeand use the same, reference being had to the accompanying drawing,forming part of this specification, in which drawing- Figure 1represents a front view of this invention. Figure 2 is a longitudinalvertical section of the same.

Similar letters indicate correspondingparts.

This invention consists in t-he arrangement of an elastic loop orspring, which is attached at one end to a hook formed on the innersurface of the roller-bracket of a curtain-fixture, while its other endis secured to apin or screw,'which also serves to guide and retain r thebracket in position, in ,such a manner that the strain of the elasticloop or spring keeps the cord, by means of which the curtain isoperated, taut, and at a uniform tension; and, at the same time, therollerbracket, being retained simply by one pin or screw, is free toaccommodate itself to the` position of the pulley at the end of thecurtain-roller, and, by these means, a roller-bracket is produced, whichis very cheap in its construction, which can be fastened in roller a.

From the inner surface of the bracket A projects a hook, l, which, bypreference, is produced by punching in a portion of the bracket, asshown in the drawing, but which might be made separate from the bracket,and attached to the same in any desirable manner.

From this hook extends an elastic loop or spring,

c, to a pin, or screw, tl, which passes freely through a slot, c, in theface side of the bracket, and is fastened in th'e window-frame. A

A If. the spring c is released from the hook b, the bracket A can slideup and down as far as the slot e will permit, and if the spring isattached to the hook, it has a tendency to pull the bracket downward, ortoward the pin d.

From the pulley a extends an endless cord, f, over a pulley, g, securedto the end of the curtain-roller, and the bracket A is adjusted in sucha position that the spring c will subject the cord f to a certaintension, suficient to retain the curtain in any desired position.

By these means, a curtain-fixture is obtained, which is very simple andcheap, and which, being fastened to the window-frame by one pin only,passing freely through the slot c, is free to accommodate itself to theposition of the pulley on the end of the curtainroller, while, at thesame time, the cord f is always keptat a proper tension.

\Vhat I claim as new, and desire t0 secure by Letters Patent, is

The bracket A, carrying roller a, slotted at e, and having hook b, inconnection with pin d and spring c, said pin guiding thcbracket, andsupporting one end of the spring, when the parts are constructed tooperate together, substantially as described.
